Talk about how to do hardware compatibility testing and quickly migrate to openeuler?

As a free enterprise Linux operating system , since CentOS 8 Since the announcement of the end of maintenance （2021 end of the year ）, It has aroused widespread concern in the industry . The reason is , It's not just about CentOS Huge user base , And migration CentOS It is not a simple system reinstallation , Instead, it needs to replace the operating system and the application software and business system on it 、 adapter 、 Migration and refactoring . therefore , How to implement application migration efficiently, safely and with low risk , Become the core issue concerned by users .

There are many domestic operating system migration schemes , Open source operating system openEuler It is also one of the hot topics .

openEuler The kernel comes from Linux, It supports Kunpeng 、X86 And so on , It can fully release the potential of computing chips , It is widely used in database 、 big data 、 Cloud computing 、 Artificial intelligence and other application scenarios .openEuler It is also compatible CentOS One of the domestic mainstream open source operating systems , Comparison CentOS ,openEuler For key functions in the core, such as process scheduling 、 memory management 、IO Read / write is deeply optimized , At the same time, a container is built outside the core iSula、 virtualization StraitVirt、 Confidential computing SecGear、 Bi Sheng JDK Other characteristics .

openEuler Rich ecological .2021 year 11 month 9 Japan ,openEuler The community donated to the open atom open source foundation . For more than half a year , The community has more than 300+ Partners join , contain Intel、Marvel、 Xinhua third class well-known enterprises , Converging slave processors 、 The whole machine 、 Basic software 、 Application software 、 Industry customers and other partners in the whole industry chain . At present, there are domestic and foreign 14 Home mainstream OSV（ kirin 、 Tongxin 、 Kirin Shinan 、SUSE、 Puhua et al ） Have been released based on openEuler Commercial distribution of the operating system ; And the products have been widely distributed to the government 、 Operator, 、 Finance 、 The core system of many industries such as electric power .

today , We use X86 Take hardware compatibility as an example , Let's talk about how to migrate the operating system to openEuler（ The version of this case is openEuler 20.03 LTS SP1）.

One Environmental statement

The hardware is shown in the following table ：

project	explain
The server	2288H V5
CPU	Inter(R) Xeon(R) Gold 6266C CPU @ 3.00GHz
NIC card	CX5（CX5 Network card is mellanox A network card produced by the company ）
RIAD card	LTS SAS 3108（3108raid The card is produced by Huawei raid card ）

The operating system is as follows ：

project	explain
Centos Linux	7.9.2009（Core)
Kernel	3.10.0 x86_64

Check the current system version information cat /etc/os-release

Two Software operation and hardware compatibility evaluation tool ：x2openEuler

openEuler The community provided x2openEuler Tools , With hardware evaluation 、 Software evaluation 、 Function of system configuration evaluation , The hardware evaluation is for centos The board running normally on the system is openEuler Upper compatibility , Tool acquisition board information generation html The report , Visually and quickly show the compatibility of hardware .

 download x2openEuler Tools ： https://www.openeuler.org/zh/other/migration/

3、 ... and Deployment tools

cd /opt/rpm -ivh x2openEuler-2.0.0-1.x86_64.rpm

Be careful ： install rpm When needed root user , And now the network is needed （ Used to download installation dependencies ） Be careful ： Follow the prompts to install dependent packages such as bzip2-devel etc. .

su x2openEulerx2openEuler redis-db -init

Enter... In sequence redis Database ip:127.0.0.1 port ：6379 Database index number （0-16）：0 password （ The tool encrypts the password ）： If redis When the password is not set or empty , Just go back .

x2openEuler init source_centos7.6-openEuler20.03-LTS-SP1.tar.gz

remarks ：x2openEuler Use rpm After the installation, it will be in /opt/x2openEuler The directory contains source_centos7.6-openEuler20.03-LTS-SP1.tar.gz This default resource bundle Need to support centos8.2 To openEuler20.03-LTS-SP1 The evaluation of , You need to get the corresponding static resource package import , If the corresponding resource package is source_centos8.2-openEuler20.03-LTS-SP1.tar.gz, Import this package command ：x2openEuler init source_centos8.2-openEuler20.03-LTS-SP1.tar.gz, Select the corresponding resource package for instructions .

Analysis of hardware evaluation results

The hardware compatibility evaluation report can directly show whether each board is compatible and whether the whole machine is compatible , If any item is not in the compatibility list, it needs to be adapted .

adopt VID、DID、SVID、SSID The quad value can determine the only board . You can see from the screenshot above , Each board can be found in the southbound compatibility list , Therefore, the hardware server is from centos Migrate to openEuler 20.03 LTS SP1 It can be implemented .
